Castiel: Jack, if you can't sleep, it's understandable given recent events.Jack: You mean dying and coming back to life.Castiel: Yeah, we've all been through it. It's something of a right of passage around here.

The Shadow: I meant what I said. I want you to suffer. I want you to go back to your normal life, to forget about this, to forget about me until you give yourself permission to be happy and when you let the sun shine on your face, that's when I'll come. That's when I'll come to drag you to nothing.Castiel: I accept.
